"I love everything about this sports bra! It fits perfectly, is super comfortable, supportive, and I really appreciate that it doesn’t have padding. For reference, I’m a 34D and ordered a medium."
"I love this bra! The fit is comfortable, flattering and functional for my training. It is a bra I could wear all day. I am usually between a small and a medium so I ordered a medium and it was too big. I exchanged for a small and it’s perfect. Will be ordering in more and would love to see a wider range of colors!"
"This is a fantastic bra. I don't dread workouts anymore because I feel supported and I don't have to worry about PFAS and endocrine disruptors. . . just good old fashioned sweat. 😉"
"I love that my shirts glide right over this smooth fabric. The band might be a smidge tight if you have wide ribs, but otherwise the fit is great and very supportive. I bought two sizes so that I can have a one a little looser for less intense activities."
"One of the best sports bras I’ve owned! Super comfy and light weight! Stays in place with intense workouts. One thing to note- there is no padding. Will be purchasing several more!"
"Love that the fabric feels like performance, love that there’s no pads, and love that it’s toxic chemical free!"
"The fit is amazing. I have not experienced any chafing whatsoever. Also have not noticed any lingering odor that most workout clothes have."
"I’ve had a hard time finding replacements for sports wear in my closet without harmful chemicals. I was happy when I tried this on. I would definitely order it again in another color!"
"I ordered size medium and it's a little small and tight, but will probably loosen up some over time."
"This bra is so soft, I’m a 34D and the medium fit perfectly"
